FIG. 1 schematically illustrates select portions of a musculoskeletal system 10 of an animal. In an embodiment, the musculoskeletal system 10 is that of a canine. However, the teachings of this disclosure may be applicable for other veterinary uses, such as for felines, for example.

Forelimb portions 12 of the musculoskeletal system 10 are specifically shown in FIG. 1. Each forelimb portion 12 includes, among other bones, a scapula 14, a humerus 16 positioned distally of the scapula 14, and a radius 18 and an ulna 20 positioned distally of the humerus 16. The humerus 16 interfaces with the scapula 14 to establish a shoulder joint of the animal, and the radius 18 and the ulna 20 interface with the humerus 16 to establish an elbow joint of the animal.

As schematically illustrated, a fracture 22 may occur in a distal section 24 of the humerus 16, such as in response to a traumatic impact. The distal section 24 may be simply referred as the distal humerus. The fracture 22 may present as a lateral fracture pattern (see FIG. 2(a)), a medial fracture pattern (see FIG. 2(b)), a “Y” type fracture pattern (see FIG. 2(c)), or a “T” type fracture pattern (see FIG. 2(d)). Whatever pattern exhibited by the fracture 22, the fracture 22 typically must be repaired in order to alleviate pain and facilitate proper bone healing. The fracture 22 may be repaired using a bone plate. This disclosure is therefore directed to bone plate designs that are suitable for repairing distal humerus fractures of animals (e.g., non-humans such as canines and felines).

FIGS. 3-7 illustrate an exemplary bone plate 26 for repairing a bone defect, such as a fracture 22 of a distal section 24 of a humerus 16 of an animal, such as a canine or feline, for example. The bone plate 26 is shown alone in FIGS. 3, 4, and 5, and the bone plate 26 is shown positioned relative to the distal section 24 of the humerus 16 in FIG. 6.

The bone plate 26 may extend along a longitudinal axis A between a shaft portion 28, located proximally when the bone plate 26 is implanted, and a head portion 30, located distally when the bone plate 26 is implanted (see, e.g., FIG. 6). The shaft portion 28 and the head portion 30 establish a single-piece bone plate structure.

The bone plate 26 includes an overall length L1. The overall length L1 may be specifically sized for use relative the distal section 24 of the humerus 16 of a canine or a feline, for example.

The shaft portion 28 may include a length L2, and the head portion 30 may include a length L3. In an embodiment, the length L2 is larger than the length L3.

The head portion 30 may be broader than the shaft portion 28. For example, the head portion 30 may include a maximum width W1 that is larger than a maximum width W2 of the shaft portion 28.

The head portion 30 may extend at an inclined angle relative to the shaft portion 28. In an embodiment, the head portion 30 is angled at an inclined angle α of between about 10 degrees and about 15 degrees relative to the shaft portion 28 (see FIG. 5). In this disclosure, the term “about” means that the expressed quantities or ranges need not be exact but may be approximated and/or larger or smaller, reflecting acceptable tolerances, conversion factors, measurement error, etc.

The bone plate 26 may further include a bone contacting surface 32 and an outer surface 34 on an opposite side of the bone plate 26 from the bone contacting surface 32. The bone contacting surface 32 may include a slightly concave curvature for conforming to the contour of the distal section of 24 of the humerus 16.

The shaft portion 28 may include a plurality of openings 36 configured for receiving fixation devices (e.g. screws, etc., not shown in FIGS. 3-6) for fixating the bone plate 26 to the distal section 24 of the humerus 16. The openings 36 extend completely through the shaft portion 28 and therefore open through both the bone contacting surface 32 and the outer surface 34. In an embodiment, the shaft portion 28 includes four openings 36 that are equally sized and aligned relative to one another along the longitudinal axis A. However, other configurations are also contemplated, and thus the total number of openings 36 and their specific arrangement within the shaft portion 28 are not intended to limit this disclosure.

The shaft portion 28 may additionally include one or more K-wire holes 38 configured for receiving a K-wire (not shown) in order to temporarily secure the bone plate 26 to the distal section 24 of the humerus 16 prior to achieving final fixation via fixation screws. The K-wire holes 38 extend completely through the shaft portion 28 and therefore open through both the bone contacting surface 32 and the outer surface 34. The total number of K-wire holes 38 provided in the shaft portion 28 is not intended to limit this disclosure.

The head portion 30 may be bounded by a peripheral edge 40. The peripheral edge 40 may connect to and extend outwardly of a first side 50 of the shaft portion 28 to establish a curved expanded section 42 of the head portion 30. From the curved expanded section 42, the peripheral edge 40 may continue linearly to establish a straight distal section 44 of the head portion 30. The peripheral edge 40 may extend from the straight distal section 44 about a curved edge 46 and then linearly along a straight section 48 that is positioned on an opposite side of the head portion 30 from the curved expanded section 42. The straight section 48 may connect to a second side 52 of the shaft portion 28.

A first opening 54 may be formed through the head portion 30 at a location that is proximate to the curved expanded section 42. The first opening 54 may extend completely through the head portion 30 and therefore opens through both the bone contacting surface 32 and the outer surface 34. The first opening 54 may be configured to receive a transcondylar screw that allows for the capture of both condyles 56 of the distal section 24 of the humerus 16 with a single screw.

A second opening 58, a third opening 60, and a fourth opening 62 may be formed through the head portion 30 at a location that is proximate to the straight section 48. The second opening 58, the third opening 60, and the fourth opening 62 may extend completely through the head portion 30 and therefore open through both the bone contacting surface 32 and the outer surface 34. Each of the second opening 58, the third opening 60, and the fourth opening 62 is configured for receiving a fixation device (e.g. a screw, etc., not shown in FIGS. 3-6) for fixating the bone plate 26 to the distal section 24 of the humerus 16.

In an embodiment, the second opening 58, the third opening 60, and the fourth opening 62 are equally sized openings. In another embodiment, the first opening 54 is larger in diameter compared to any of the second opening 58, the third opening 60, or the fourth opening 62.

Each of the first opening 54, the second opening 58, the third opening 60, and the fourth opening 62 may be an angled opening that positions a fixation screw received therein within a safe corridor across one of the condyles 56 of the distal section 24 of the humerus 16. In an embodiment, the openings 54, 58, 60, 62 extend at an angle Θ relative to a transverse axis 64 that extends vertically through the head portion 30 (see FIG. 7). The transverse axis 64 is perpendicular to the longitudinal axis A of the bone plate 26. In an embodiment, the angle Θ is about 10 degrees. However, other angles may also be suitable.

The head portion 30 may additionally include an elliptical hole 66. The elliptical hole 66 may be sized and shaped for accommodating at least a portion of one of the condyles 56 of the distal section 24 of the humerus 16, thereby providing a better anatomic fit. The elliptical hole 66 may extend completely through the head portion 30 and therefore opens through both the bone contacting surface 32 and the outer surface 34. In an embodiment, the elliptical hole 66 is positioned axially between the first opening 54 and the second, third, and fourth openings 58, 60, 62.

The head portion 30 may additionally include one or more K-wire holes 38 configured for receiving a K-wire (not shown) in order to temporarily secure the bone plate 26 to the distal section 24 of the humerus 16 prior to achieving final fixation via fixation screws. The K-wire holes 38 extend completely through the head portion 30 and therefore open through both the bone contacting surface 32 and the outer surface 34. The total number of K-wire holes 38 provided in the head portion 30 is not intended to limit this disclosure.

A relief 68 (see FIG. 4) may be formed in head portion 30 on the bone contacting surface 32 of the bone plate 26. The relief 68 may be disposed slightly proximally of the elliptical hole 66 and the first opening 54. The relief 68 may be sized and shaped to provide clearance over a soft tissue anatomy of the distal section 24 of the humerus 16.

A plurality of scalloped portions 70 (see FIGS. 4 and 5) may be formed in the shaft portion 28 on the bone contacting surface 32 of the bone plate 26. The scalloped portions 70 are configured to minimize bone contact at certain locations of the bone plate 26, thereby creating a constant stiffness across the bone plate 26 when implanted.

The longitudinal axis A may bisect the shaft portion 28 into two equal sections such that the shaft portion 28 is substantially symmetrical about the longitudinal axis A. The head portion 30 may be asymmetrically disposed about the longitudinal axis A. In an embodiment, the longitudinal axis A may intersect through an edge of each of the second, third, and fourth openings 58, 60, and 62 of the head portion 30 (see FIG. 3).

The bone plate 26 may be made from any biocompatible material or combination of biocompatible materials. Exemplary materials that may be suitable for manufacturing the bone plate 26 include, but are not limited to, titanium, titanium alloys, stainless steel, thermoplastic materials, etc.

The various openings 36, 58, 60, and 62 of the bone plate 26 may be configured to receive fixation screws of any size (e.g., 2.0 mm, 2.4 mm, etc.), and some openings could be sized differently than the other openings. Thus, the specific sizes of the openings of the bone plate 26 are not intended to limit this disclosure.

In the above embodiment, the bone plate 26 is shown and described as having a right orientation. However, the bone plate 26 could also be provided in a left orientation, with such a bone plate being the mirror image of the right orientated bone plates described above. FIGS. 8(a), 8(b), and 8(c) illustrate an exemplary bone plate 26-2 having a left orientation.

FIGS. 9-13 illustrate another exemplary bone plate 126 for repairing distal humerus fractures of an animal, such as a canine or a feline, for example. As will become more apparent from the description below, the bone plate 126 is similar to the bone plate 26 of FIG. 3-7 but includes some additional/modified features. The bone plate 126 is shown alone in FIGS. 9, 10, and 11, and the bone plate 126 is shown positioned relative to a distal section 24 of a humerus 16 in FIG. 12.

The bone plate 126 may extend along a longitudinal axis A between a shaft portion 128, located proximally when the bone plate 126 is implanted, and a head portion 130, located distally when the bone plate 126 is implanted (see, e.g., FIG. 12). The shaft portion 128 and the head portion 130 establish a single-piece bone plate structure.

The bone plate 126 includes an overall length L1. The overall length L1 may be specifically sized for use relative the distal section 24 of the humerus 16 of a canine or a feline, for example.

The shaft portion 128 may include a length L2, and the head portion 130 may include a length L3. In an embodiment, the length L2 is larger than the length L3.

The head portion 130 may be broader than the shaft portion 128. For example, the head portion 130 may include a maximum width W1 that is larger than a maximum width W2 of the shaft portion 128.

The head portion 130 may extend at an inclined angle relative to the shaft portion 128 (see FIG. 11). In an embodiment, the head portion 130 is angled at an inclined angle α of between about 10 degrees and about 15 degrees relative to the shaft portion 128. In another embodiment, the inclined angle α is about 13 degrees for allowing the bone plate 126 to better accommodate the animal's anatomy.

The bone plate 126 may further include a bone contacting surface 132 and an outer surface 134 on an opposite side of the bone plate 126 from the bone contacting surface 132. The bone contacting surface 132 may include a slightly concave curvature for conforming to the contour of the distal section of 24 of the humerus 16.

The shaft portion 128 may include a plurality of openings 136 configured for receiving fixation devices (e.g. screws, etc., not shown in FIGS. 9-12) for fixating the bone plate 126 to the distal section 24 of the humerus 16. The openings 136 extend completely through the shaft portion 128 and therefore open through both the bone contacting surface 132 and the outer surface 134. In an embodiment, the shaft portion 128 includes five openings 136 that are equally sized and spaced along the longitudinal axis A. However, other configurations are also contemplated, and thus the total number of openings 136 and their specific arrangement within the shaft portion 128 are not intended to limit this disclosure.

The shaft portion 128 may additionally include one or more K-wire holes 138 configured for receiving a K-wire (not shown) in order to temporarily secure the bone plate 126 to the distal section 24 of the humerus 16 prior to achieving final fixation via fixation screws. The K-wire holes 138 extend completely through the shaft portion 128 and therefore open through both the bone contacting surface 132 and the outer surface 134. The total number of K-wire holes 138 provided in the shaft portion 128 is not intended to limit this disclosure.

The shaft portion 128 may include a proximal tip section 180 and a distal straight section 182. The proximal tip section 180 may be angled relative to the distal straight section 182 to establish a slight kickout within the shaft portion 128 for providing a more optimized screw placement. The proximal tip section 180 may extend at an angle γ relative to the distal straight section 182. In an embodiment, the angle γ is between about 3 degrees and about 18 degrees. In another embodiment, the angle γ is about 8 degrees. However, the angle γ may be optimized for suitability relative to any type of animal.

A proximal most opening of the openings 136 may be formed through the proximal tip section 180, and the remaining openings 136 may be formed through the distal straight section 182. However, other configurations are alternatively possible.

The head portion 130 may be bounded by a peripheral edge 140. The peripheral edge 140 may connect to and extend outwardly of a first side 150 of the shaft portion 128 to establish a curved expanded section 142 of the head portion 130. From the curved expanded section 142, the peripheral edge 140 may continue linearly to establish a straight distal section 144 of the head portion 130. The peripheral edge 140 may extend from the straight distal section 144 about a curved edge 146 and then linearly along a straight section 148 that is positioned on an opposite side of the head portion 130 from the curved expanded section 142.

An outcropped section 184 of the peripheral edge 140 may be positioned between the straight section 148 and a second side 152 of the shaft portion 128. The outcropped section 184 provides increased plate material in the head portion 130 for maximizing and optimizing bone purchase.

A first opening 154 may be formed through the head portion 130 at a location that is proximate to the curved expanded section 142. The first opening 154 may extend completely through the head portion 130 and therefore opens through both the bone contacting surface 132 and the outer surface 134. The first opening 154 may be configured to receive a transcondylar screw that allows for the capture of both condyles 56 of the distal section 24 of the humerus 16 with a single screw.

A second opening 158 and a third opening 160 may be formed through the head portion 130 at a location that is proximate to the straight section 148. The second opening 158 and the third opening 160 may extend completely through the head portion 130 and therefore open through both the bone contacting surface 132 and the outer surface 134.

A fourth opening 162 may be formed through the head portion 130 at a location that is proximate to the outcropped section 184. In an embodiment, the fourth opening 162 is the proximal most opening formed in the head portion 130. The fourth opening 162 may extend completely through the head portion 130 and therefore opens through both the bone contacting surface 132 and the outer surface 134. Each of the second opening 158, the third opening 160, and the fourth opening 162 is configured for receiving a fixation device (e.g. a screw, etc., not shown in FIGS. 9-12) for fixating the bone plate 26 to the distal section 24 of the humerus 16.

In an embodiment, the openings 154, 158, 160, 162 extend at an angle Θ relative to a transverse axis 164 that extends vertically through the head portion 130 (see FIG. 13). The transverse axis 164 is perpendicular to the longitudinal axis A of the bone plate 126. In an embodiment, the angle Θ is about 10 degrees. However, other angles may also be suitable.

The head portion 130 may additionally include an elliptical hole 166. The elliptical hole 166 may be sized and shaped for accommodating at least a portion of one of the condyles 56 of the distal section 24 of the humerus 16, thereby providing a better anatomic fit. The elliptical hole 166 may extend completely through the head portion 130 and therefore opens through both the bone contacting surface 132 and the outer surface 134.

A relief 168 (see FIG. 10) may be formed in head portion 130 on the bone contacting surface 32 of the bone plate 126. The relief 168 may be disposed slightly proximally of the elliptical hole 166 and the first opening 154. The relief 168 may be sized and shaped to provide clearance over a soft tissue anatomy associated with the distal section 24 of the humerus 16.

A plurality of scalloped portions 170 (see FIGS. 10 and 11) may be formed in the shaft portion 128 on the bone contacting surface 132 of the bone plate 126.

The longitudinal axis A may bisect the distal straight section 182 of the shaft portion 128 into two equal sections such that the distal straight section 182 is substantially symmetrical about the longitudinal axis A. The proximal tip section 180 of the shaft portion 128 and the head portion 130 may each be asymmetrically disposed about the longitudinal axis A. In an embodiment, the longitudinal axis A may intersect through an edge of the elliptical hole 166 of the head portion 130.

The bone plate 126 may be made from any biocompatible material or combination of biocompatible materials. Exemplary materials that may be suitable for manufacturing the bone plate 126 include, but are not limited to, titanium, titanium alloys, stainless steel, thermoplastic materials, etc.
